As the efficacy of
successive product generations and new architecture efficiencies improve -
customers don't need to buy so many SSDs. The result can a revenue crash
- such as we saw happening at Fusion-io.

Samsung's earlier purchase -
NVELO (acquired in
December 2012) -
operated in the consumer
market - whereas Proximal's caching technology was designed to work with
enterprise PCIe SSDs -
a market in which Samsung is a relative newcomer - and in which Samsung
stood out from other leading
vendors in that market in having no caching software it could cal its own.
